FURNACE RADIATOR.

Application filed June 14,

7 increasing the radiating surface within a furnace and is particularlyadaptable to furnaces for houshold heating purposes and the likeemploying an oil burner.

It is the usual procedure in installing an oil burner to employ thepresent furnace with the customary combustion chamber and radiating domeabove, but with such installation, particularly where the oil isatomized by air pressure there is a resultant high stack loss, as theair forced into the furnace rushes through the combustion chamber, andinto the stack thereby carrying out an undue amount of heat that is solost on account of sufficient radiating surface not being presentbetucenthe combustion chamber and the stack, and it is the primary purpose ofproviding a radiating unit that may be easily and cheaply interposedwithin the furnace between the combustion chamber and the stack. I

Reference is made to theaccompanying drawing, in which- Fig. 1, is arear elevation of the radiating unit; I

Fig. 2, a top plan view of the radiating unit;

Fig. 3, a. transverse section through the radiating unit on the line 38in Fig. 1; and

Fig. 4, a fragmentary side elevation of a furnace with the radiatingunit in place.

Like characters of reference indicatelike. parts throughout the severalviews.

Referring first to Fig. 1, of the drawing, a furnace of simplifiedconstruction is here shown to illustrate in a more or less diagrammaticmanner the installation of the radiating unit in reference tothe furnaceparts. The furnace here shown has the usual and well known centralheater with the gas and smoke outlet through the top .into the pipe 11and the heater 10 is surrounded by the housing 12 with the usualairspace therebetween such that, air may pass about the heater 10 to beheated and out through the riser holes 18. The housing 12 is made asusual out of a plurality of vertically joined sections which are boltedtogether at the joints, not shown.

A smoke pipe 1 1 leads from the pipe 11, and customarily leads directlyto the stack (not shown), but in this invention, such a stack connectionis not made, and instead,

the pipe 1 1 leads forwardly to an upper manifold 15 having a continuouspassage th rearound. j l

A plurality of flues 16 extend downwardly from the top manifold 15 todischarge into a substantially U-shaped manifold 17 below, and adischarge pipe 18 leads from the lower manifold 17 to any suitable stackconnecting means.

Referring again to Fig. 4, an oil burner tube 19 is shown projectinginto the combustion heater 10 near the bottom. Such tube may beintroduced into the heater 10 at a higherelevation as indicated by thedotted lines if desired. In either event, the combustion of the oiltakes place within the heater 10 and the hot gases, including the excessair used to atomize the oil and not required to support combustion, passupwardly out through the pipe 11, the pipe 1 1, and

into the top manifold 15, from which the gases are distributed to escapedownwardly through the fines 16 into the lower manifold '17 and finallybe discharged outwardly through the pipe 18.

It is obvious that a large heated surface including both top and bottommanifolds and fines is thus exposed within the furnace housing 12 toradiate the heat therefrom and warm the air passing through the housingand thus utilize heat that would otherwise belost.

It is to be noted that the manifolds 15 and 17 are shaped so as topermit the radiating unit to be slipped about the outside of the heater10. This is accomplished by unbolting the sections at their verticaljoints and lifting as many of the sections away as may be foundnecessary. Then the manifold unit is raised until its top member 15 willclear the pipe 1 1, and by a sliding side movement the manifold unit isput in proper vertical relation with the furnace and then lowered tofinal position as shown in Fig. 4E. The end of pipe 14 is inserted inthe pipe 11, and then the housing sections are re placed with the pipe18 passing through the housing as shown in Fig. 1, and the pipe '18 isconnected with the chimney in the usual manner.

- Having described my invention in one particular form, I do not desireto be limited to the precise structure so shown, nor any more than maybe required by the foliii lowing cluinn since it is obvious that manstructural rurintions may be had without departing from the spirit ofthe invention.

I claim:
